Question From A Buddy About His 03 Cobra

BDaily · December 26th, 2011, 04:22 PM

Like the title says my buddy has an 03 cobra and is having a rough time trying to get it running again. He had to pull and rebuild the motor due to the car going lean and melting a piston. He has it back together and it is still going lean on bank 2 throwing the code. He just replaced the O2 sensors, checked the plugs and replaced them and replaced the coils. What could be causing this condition? Also he is getting oil into the intake and plenum/throttle body. What is the problem?

Thanks
Bryan.

get it to a tuner to see what the fuel table is doingand what the MAF is doing. Oil problem is probly PCV related. Get an Air/Oil separator from JLT or someone to clear that up.
